Wool is an ideal insulation product in van builds or touring vehicles that are being slept in, where wall cavities or hollows in beams etc need to be filled with an insulation product. Being a natural product, wool is non-toxic and actually acts as a natural form of air filtration. 

Why wool?

  • Moisture and climate control – moisture and mold happens in your walls. Wool absorbs and adsorbs it against 65% relative humidity.
  • Suppresses mold and mildew – natural keratin prevents against the spread of mold and mildew.
  • Thermal conductivity and absorbs sound.
  • Resists fire – wool will not support a flame below 1100F; conforms to Class A of the ASTM E84 test.
  • All natural – wool insulation is entirely renewable and sustainable.
  • Wool filters the air and improves indoor air quality.  The amino acids in wool irreversibly bond with formaldehyde, NOₓ and SO2 on a molecular level.
  • Long lasting – inherent characteristics allow stated R-values to exceed other forms of insulation.
  • No off-gassing – natural characteristics make our insulation devoid of harmful chemicals.

The results of wool are long lasting, non-slumping, high performance insulation that keeps your walls dry and temperatures more constant.
